WebMost tsunamis are generated by earthquakes with magnitudes over 7.0 that occur under or very near the ocean and less than 100 kilometers (62 miles) below Earth's surface (earthquakes deeper than this are unlikely to displace the ocean floor). Generally, an earthquake must exceed magnitude 8.0 to generate a dangerous distant tsunami.
